Lazy lists in Compose
Stay organized with collections
Save and categorize content based on your preferences.
Compose gives you a simpler and more performant way to create scrolling lists,
using fewer lines of code than RecyclerView. Learn how to use lazy
layouts to create lists that let you add content to lists, on demand.
Key points
- Use lazy layouts to add content on demand for a significant number of items
or large datasets, increasing your app's performance and responsiveness.
- This approach lets you focus on describing your item content while lazy
lists handle everything else.
- You can describe one item using the
item() block or multiple items
with the items() block.
LazyListState is an important state object that stores the scroll
position and contains useful information on your list.
